Form for renewal visa

I am a French citizen and a Peruvian resident.  I am currently in the US on a travel visa and need to leave the country in order to renew my travel visa.  Does travel to Mexico qualify for me to renew my travel visa back to the States? Thanks

I am indian national with a valid passport. My 10 years valid US visa is expiring in july. How can I renew it. Should I also pay visa fees

I have multiple entry for two years it expired  on  11feb 2010.can I renew by sending through the post or what can I do?
